Newton's Cradle is a classic desk toy. Also known as "Balance Balls", "Newton's Pendulum", "Kinetic Balls" and "Newton's Balls", this executive office toy demonstrates the law of conservation of momentum. The motion of this 5-ball cradle is the most addicting way to demonstrate Newton's law of conservation of momentum and energy.
